When you get off the bus at the beginning look for the broken down gas station which is to your left past the claptrap. Search the gas station when it is your turn to move and you will find several money crates including a weapon chest on top of the building.
During the tour at the start of the game follow the robot to the small campsite with the raised car next to the burning tires. On the way there collect ALL the guns and money and kill ALL the enemies. When you have done this pause gameplay and select 'Exit' and your character will be saved with the current items and experience. Then load the saved game so you start at the beginning again and repeat the procedure as many times as desired.
In the Rust Commens West there is a secret weapons box that is out of bounds and has really rare weapons/items in it. First go to Rust Commons West's underpass new U station. Then make a vehicle. Next drive the vehicle down the road to the rock formation that looks like a bridge over the road. Go under the underpass and turn right. Keep going until you reach a giant column with a turret attached. Get out of the vehicle (note: if you don't you will die) and use the rocks to the left of the column to get next to (this is the only way to get to it). Then facing out to the wastelands below go to the right of the column and look down toward the edge of the rocks. You should see a small/medium sized rock ledge. Jump down to it then jump down to the next one below it. A warning sign should come up about mid-jump. When you land on the big rock plateform below the ledges go around the corner and there should be a red weapons box there. This weapons box has the rarest items in the game and can be gotten every time you exit your game. (note: the only way to get back to the rest of the game is to run off the ledge and die or exit the game there is no other way back up)
Bandit Treasure Quest: Go to Old Haven and follow the left wall until you eventually reach a pile of dead bandits where one of them is breathing his last few breaths. When he opens his hand he will be holding a glowing strongbox key that will start the quest. Make sure you have a corrosive weapon or two and some health packs because you're going to need them as you search Old Haven for the other two keys.
Green Thumb Quest: Go to the Middle of Nowhere Bounty Board. Get a car from Scooter's and drive to the right. Notice the small shack with big plants around it. Talk to the man leaning against the shack to start the quest. Then travel across the bridge to the east side of Rust Commons East. Follow your map marker to the valve. Avoid the small bandit camp set up near the valve. Drive to Jaynistown and attach the valve to the marked pipe in order to turn off the water.
First, you need to join a friend's game, then you'll need to drop all of your equipment or just the ones you want to duplicate, then have your friend kick you out or some other method other than exiting by yourself, because if you do, you'll permenately lose your equipment. After your friend invites you back, all your stuf will be where it is and then when you check your equipment, youll still have your equipment. You can then sell the duplicates, using this, you can get the Pandora-Dog Millionaire easily. You can do this as many as disired.
